This extends the earlier approach to stream a large file directly from the
filesystem to its own packfile, and allows "git add" to send large files
directly into a single pack. Older code used to spawn fast-import, but the
new bulk-checkin API replaces it.

It is useful to be able to rewind a check-summed file to a certain
previous state after writing data into it using sha1write() API. The
fast-import command does this after streaming a blob data to the packfile
being generated and then noticing that the same blob has already been
written, and it does this with a private code truncate_pack() that is
commented as "Yes, this is a layering violation".
Introduce two API functions, sha1file_checkpoint(), that allows the caller
to save a state of a sha1file, and then later revert it to the saved state.
Use it to reimplement truncate_pack().

Factor out a small logic out of the private write_pack_file() function
in builtin/pack-objects.c.
This changes the order of finishing multi-pack generation slightly. The
code used to
- adjust shared perm of temporary packfile
- rename temporary packfile to the final name
- update mtime of the packfile under the final name
- adjust shared perm of temporary idxfile
- rename temporary idxfile to the final name
but because the helper does not want to do the mtime thing, the updated
code does that step first and then all the rest.

estimate_cache_size() tries to guess how much memory is needed for the
in-memory representation of an index file. It does that by using the
file size, the number of entries and the difference of the sizes of the
on-disk and in-memory structs -- without having to check the length of
the name of each entry, which varies for each entry, but their sums are
the same no matter the representation.
Except there can be a difference. First of all, the size is really
calculated by ce_size and ondisk_ce_size based on offsetof(..., name),
not sizeof, which can be different. And entries are padded with 1 to 8
NULs at the end (after the variable name) to make their total length a
multiple of eight.
So in order to allocate enough memory to hold the index, change the
delta calculation to be based on offsetof(..., name) and round up to
the next multiple of eight.
On a 32-bit Linux, this delta was used before:
sizeof(struct cache_entry) == 72
sizeof(struct ondisk_cache_entry) == 64
---
8
The actual difference for an entry with a filename length of one was,
however (find the definitions are in cache.h):
offsetof(struct cache_entry, name) == 72
offsetof(struct ondisk_cache_entry, name) == 62
ce_size == (72 + 1 + 8) & ~7 == 80
ondisk_ce_size == (62 + 1 + 8) & ~7 == 64
---
16
So eight bytes less had been allocated for such entries. The new
formula yields the correct delta:
(72 - 62 + 7) & ~7 == 16

The sample pre-commit hook script would fail to reject a file name like
"a\nb" because of the way newlines are handled in "$(...)". Adjust the
test to count filtered bytes and require there be 0. Also print all
diagnostics to standard error, not stdout, so they will actually be seen.

Git for Windows comes with a bash that doesn't support process substitution.
It issues the following error when using git-completion.bash with
GIT_PS1_SHOWUPSTREAM set:
$ export GIT_PS1_SHOWUPSTREAM=1
sh.exe": cannot make pipe for process substitution: Function not implemented
sh.exe": cannot make pipe for process substitution: Function not implemented
sh.exe": <(git config -z --get-regexp '^(svn-remote\..*\.url|bash\.showupstream)$' 2>/dev/null | tr '\0\n' '\n '): ambiguous redirect
Replace the process substitution with a 'here string'.

Rather nasty things happen when a mutex is not initialized but locked
nevertheless. Now, when we're not running in a threaded manner, the mutex
is not initialized, which is correct. But then we went and used the mutex
anyway, which -- at least on Windows -- leads to a hard crash (ordinarily
it would be called a segmentation fault, but in Windows speak it is an
access violation).
This problem was identified by our faithful tests when run in the msysGit
environment.
To avoid having to wrap the line due to the 80 column limit, we use
the name "WHEN_THREADED" instead of "IF_USE_THREADS" because it is one
character shorter. Which is all we need in this case.
